i dont think anything is wrong i just bought it did a compression test no1-150psi no2-155 psi no3-155psi no4-155psi no5 155psi no6-155psi i put a couple of drips of oil in the cylinder no1 and it went up 5psi is that bad? it is meant to have slightly bigger cams in it oil pressure is about 2 at 1000rpm and goes up to 4 at about 3500rpm-4000rpm
